ABSTRACT

Automatic swimming pool cleaners may include cable storage systems for storing an electrical cable on, in, or near a body of the automatic swimming pool cleaner. Some cable storage systems may include a cable storage device on the body of the automatic swimming pool cleaner and/or on a cover for the body of the automatic swimming pool cleaner. Cable storage systems may additionally or alternatively include a cable storage device on the electrical cable. The automatic swimming pool cleaners may be configured and balanced to be supported by their rear portions essentially upright when stored.

REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 63/182,113, filed on Apr. 30, 2021 and entitled CABLE STORAGE CONCEPTS PRINCIPALLY FOR USE IN CONNECTION WITH AUTOMATIC SWIMMING POOL CLEANERS, the content of which is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

This invention relates to equipment for use in connection with water-containing vessels such as swimming pools and spas and more particularly, but not necessarily exclusively, to equipment, systems, and methods for storing cables on automatic swimming pool cleaners (“APCs”) configured to operate within the vessels.

BACKGROUND OF THE INVENTION

Numerous cleaning devices capable of autonomous movement within swimming pools and spas currently exist. The most common of these devices are APCs, which often are either hydraulic or robotic in type. Hydraulic cleaners vary water flow for movement, while robotic cleaners typically employ electric motors to cause motion. Hydraulic APCs, furthermore, subdivide into “pressure-side” and “suction-side” cleaners, with pressure-side cleaners being fluidly connected to outputs of pumps of pool water circulation systems and suction-side cleaners being fluidly connected to inputs of such pumps.

Although some robotic APCs include on-board batteries for powering the electric motors, many do not. Instead, these cleaners receive electricity through electrical cables (referred to herein as “cables” or “flexible cables”) attached to their bodies. U.S. Pat. No. 10,876,315 to Pichon, et al. (“Pichon”), whose contents are incorporated herein in their entirety by this reference, illustrates an exemplary robotic APC to whose body a flexible cable is attached. See Pichon, col. 4, 11. 60-63. As noted in the Pichon patent, the flexible cable may be directly or indirectly “connected to the electric current at the mains supply,” see id., 11. 63-67, and the cable may have “length of approximately 10 [meters] or so,” see id., col. 5, 11. 3-4. Further described in the Pichon patent is a winder distinct from the APC. In use, the winder may wind the flexible cable onto a reel so as to extract the APC from a swimming pool.

As such, the cables typically are elongated so as not to impede travels of the APCs within pools. However, the elongated nature of these electrical cables equally makes them difficult to store when not in use.

Moreover, the cable stowed on the APC itself using the systems and methods described herein may avoid any need for a separate winder and/or accessories on a trolley for the APC to store the cable. In some embodiments, the APCs may include a manual or automatic winding assembly for facilitating storage of the cables on the APC. Various other benefits and advantages may be realized with the systems and methods provided herein, and the aforementioned advantages should not be considered limiting.

FIGS. 1 and 2 illustrate an APC 10 with a cable storage system 11 according to embodiments. The APC 10 generally includes a body 18 with a first end 19 and a second end 21. One or more motive elements 30 (e.g., wheels 33, tracks, rollers, feet, combinations thereof, etc.) are provided with the body 18 for moving the APC 10 along a surface (such as, but not limited to, a floor or wall of a swimming pool or spa). The APC 10 may also include various cleaning devices or mechanisms such as but not limited to brushes or rollers 34. In certain embodiments, the rollers 34 are provided with at least one of the ends 19, 21 and optionally facilitate balancing of the APC 10 in a storage orientation as discussed in detail below. The body 18 of the APC 10 may define an interior cavity or housing area for housing various components of the APC 10, including but not limited to a pump, filters, motor block, controller, combinations thereof, and/or various other components or combinations of components as desired. Optionally, a cover 14 may be provided on a top of the body 18 (or any other location on the APC 10 as desired) such that the housing area within the body 18 may be accessed as desired.

As illustrated in FIGS. 1 and 2, the APC 10 includes a cable 26 that may supply electricity to the APC 10 and/or enable a transmission of data to or from the APC 10. An end of cable 26 may be permanently or removably attached to the APC 10.

In various embodiments, the cable storage system 11 may facilitate storage of the cable 26 on, in, or near the body 18 of the APC 10. In the embodiment of FIGS. 1 and 2, the cable storage system 11 includes a storage device 22 for selectively engaging the cable 26 and facilitating storage of the cable 26 on the body 18. In the embodiment of FIGS. 1 and 2, the storage device 22 is a hook 23 extending outwards from the body 18. However, in other embodiments, the storage device 22 may be other suitable devices or mechanisms as desired. As an example, a clip may be used in place of or in addition to the hook 23, and the clip optionally extends outwards from the body 18. Moreover, while a single storage device 22 (e.g., hook 23) is illustrated, in other embodiments, the cable storage system 11 may include any number of storage devices 22 as desired and at various locations as desired. As an example, a second hook may be provided proximate to the second end 21 and facing a direction opposite of the hook 23 illustrated in FIGS. 1 and 2. When a plurality of storage devices 22 are included, the storage devices need not be the same type of storage device 22. As an example, one storage device may be the hook 23 and another storage device 22 may be a clip or clasp. Other types of storage devices 22 and combinations of storage devices 22 may be used as desired.

The hook 23 (or other storage device 22) may be connected to any suitable component or region of the body 18 as desired, and in the embodiment illustrated the hook 23 is provided on the cover 14. As such, while the hook 23 is illustrated protruding upward from the cover 14 and more proximate to the first end 19, it need not be in other embodiments. As discussed in detail below, the hook 23 protruding upward from the cover 14 may facilitate storage of the cable 26 when the APC 10 is an a storage orientation.

The hook 23 (or other storage device 22) may be permanently attached to the body 18 or component of the APC 10, although in other embodiments the hook 23 may be removably attached using various suitable mechanical fasteners and/or other techniques as desired. As illustrated in FIGS. 1 and 2, the cable 26 may be wound around hook 23 (or other storage device 22) for storage. In some embodiments, the cable storage system 11 may store the cable 26 when not in use. However, in other embodiments, cable storage system 11 may be used to store all or a portion of the cable during operation of the APC 10 and/or as otherwise desired. As an example, the cable storage system 11 may store a complete or partially floating cable (and may completely or partially store such cable).

In various embodiments, the APC 10 may be configurable between an operating orientation (FIG. 1) and a storage orientation (FIG. 2). In various embodiments, in the operating orientation, the ends 19, 21 may generally be arranged in a horizontal direction 40 and, in the storage orientation, the ends 19, 21 may generally be arranged in a vertical direction 42. In some embodiments, the APC 10 may be in the operating orientation when the APC 10 is in use on the bottom or floor or wall of a swimming pool or spa. In the operating orientation, the motive elements 30 may be in contact with the floor or wall. As an example where the motive elements 30 include the wheels as illustrated in FIGS. 1 and 2, in the operating orientation, both the wheels proximate to the first end 19 and the wheels proximate to the second end 21 may be in contact with the floor or wall. The storage orientation may be generally 90° from the operating orientation. In the storage orientation, the APC 10 may be supported and balanced by its motive elements (e.g., wheels) and/or rollers or brushes (not shown but may be similar to rollers 34) proximate to the second end 21, to aid its storage. In this position, the cable management system 11 is able to support cable 26 close to body 18, presenting a compact overall structure for APC 10.

FIGS. 3 and 4 illustrate another example of an APC 310 with a cable storage system 311 according to embodiments. The APC 310 is substantially similar to the APC 10 except that the APC 310 includes tracks 335 as motive elements 30 rather than wheels 33. In addition, a profile of the body 318 and cover 314 of the APC 310 is different than the profile of the body 18 and cover 14 of the APC 10.

As illustrated in FIGS. 3 and 4, compared to the cable storage system 11, the storage device 22 of the cable storage system 311 is a clip 337 having a cable-engagement portion 343 and an APC-engaging portion 345. In the embodiment illustrated, the clip 337 is provided on the cable 26 between an end 339 of the cable 26 connectable to an external device or system (e.g., power source, communication module or system, etc.) and an end 341 of the cable 26 connected to the APC 310. In these embodiments, the APC-engaging portion 345 may selectively engage a portion of the body 318 and/or other component of the APC 310 to store the cable 26 on the APC 310. In some embodiments, the clip 337 is movable along the cable 26 such that the clip 337 may be at various positions for engaging different portions of the body 318 or other feature of the APC 310 as desired. However, it need not be movable along the cable 26 in other embodiments.

While the clip 337 is illustrated on the cable 26, in other embodiments, the clip 337 may be provided on the body 318 and/or other component of the APC 310 for selectively engaging the cable 26.

FIG. 5 illustrates another example of an APC 510 with a cable storage system 511 according to embodiments. The APC 510 is substantially similar to the APC 10 except that a profile of the body 518 and cover 514 of the APC 510 is different than the profile of the body 18 and cover 14 of the APC 10.

Compared to the cable storage system 11, the cable storage system 511 includes a winding system or device 547 as the storage device 22 that is configured to wind up or spool the cable 26 as the winding device 547 rotates about an axis 551 when the cable 26 is not in use. In various embodiments, the winding device 547 may be an automatic winding device using various devices or mechanisms such as, but not limited to, a spring-loaded device or other suitable actuated device. In other embodiments, the winding device 547 may be a manual winding device. In the embodiment illustrated, the winding device 547 is provided within a housing cavity 549 defined by the body 518; however, in other embodiments, the winding device 547 may be provided at other locations as desired. While not illustrated in FIG. 5, as previously mentioned, other components of the APC 510 may be provided within the housing 549 such as a filter assembly, pump, motor block, etc. The particular winding device 547 illustrated in FIG. 5 should not be considered limiting, and other types of winding devices 547 may be used as desired. Moreover, in other embodiments, a cable storage system may include the winding device 547 in combination with another type of storage device 22 such as the hook 23, the clip 337, and/or as otherwise desired.
